For our science experiment, we made a hydraulic arm. It first seemed simple, then when we started doing it, it seemed intimidating. However, after we cut out the cardboard we knew we were getting somewhere. We glued all the cardboard together, and then asked our parents for some help drilling out holes in the syringes. Then we coloured the water and put them in the syringes. Then we put it all together. Until it worked properly. In the end, we were proud of our project and had a fun time using it.
